Ingersoll-Rand 66605X-X Trouble Shooting, Dimensional Data, Product discharged from air exhaust

TROUBLE SHOOTING

Product discharged from air exhaust.

SCheck for diaphragm rupture.

SCheck tightness of (6) diaphragm nut.

Air Bubbles in Product Discharge.

SCheck connections of suction plumbing. S Check band clamps on intake manifold.

S Check “O” rings between intake manifold and fluid caps. S Check tightness of (6) diaphragm nut.

Pump blows air out main exhaust when stalled on either stroke.

SCheck “U” cups on (111) spool in major valve.

SCheck (141) valve plate and (140) insert for wear.

SCheck (103) sleeve and (2) “O” ring on diaphragm connecting rod. S Check (119) “O” rings on (118) piston for wear.

Low output volume.

SCheck air supply.

SCheck for plugged outlet hose.

SFor the pump to prime itself, it must be mounted in the vertical posi-

tion so that the balls will check by gravity.

SCheck for pump cavitation -- suction pipe should be 1/2” min. or larg- er if high viscosity fluids are being pumped. Suction hose must be

non-collapsible type, capable of pulling a high vacuum.

SCheck all joints on intake manifolds and suction connections. These must be airtight.

SCheck for sticking or improperly seating check valves.

SIf pump cycles at a high rate or runs erratically, check (119) piston “O” rings for wear.
